The 30-year-old actress was terrified of taking on the role of Marilyn, at first.

“I knew I wouldn’t be able to resist, eventually,” Michelle tells UK’s Daily Mail. “Physically and vocally, everything about her is different from me. I’ve kind of gone to school and had teachers to help me understand Marilyn, so I could project an essence of her.”

The flick, which will shoot for seven weeks at Pinewood Studios and on location in and around London, chronicles a week in the life of Marilyn in which she escapes the shackles of her Hollywood career and embraces life with Brit Colin Clark (Eddie Redmayne).

Jennifer recently explained why she left her Sony music label. She shared, “It’s no secret [that] since Tommy Mottola left [in January 2003], I felt a little bit like an orphan over at Sony because he was such a big part of my first four albums and I just, you know, didn’t even really speak to anybody else at the label. He was my guy; me, [my manager Benny Medina], him. And then he was gone, and I was there, and I had no relationship with anyone else over there. Then they changed people like, three times over the next four or five years and so, we never could really get traction over at Epic Records. It was weird.”

Momager Dinaapproved of the pictures yesterday: “It was very tastefully done. Trust me. I wouldn’t have sent my 14-year-old to the set [if the shoot was in bad taste]. And obviously Lindsay wouldn’t do anything with her sister there, that was risqué.”
